I'm not going to try to convince you you're wrong. You can change you own mind about this, but it takes investment. Many, many people have found that journey toward "getting art" to be life enriching.

I'll say that for me, what blows my mind about modern and contemporary art is the willingness of individual artists to follow a conceptual idea waaay beyond what is reasonable. Whether the destination ends up being critically acclaimed is beside the point. You have to at some point be able to not care in order to play, because artists, more than anybody, know just how much of a crapshoot it is to get commercial attention.
